Product details

Overview

BC807-40W/ZLF from Nexperia is a PNP general-purpose bipolar junction transistor in SOT323 (SC-70) package, rated for −45 V V_CEO, −500 mA I_C, and DC current gain (h_FE) of 250–600 at V_CE = −1 V and I_C = −100 mA. It serves as a compact, surface-mount switching or linear amplification device in space-constrained consumer and industrial PCBs.

For engineers reviewing the BC807-40W/ZLF datasheet, BC807-40W/ZLF pinout, BC807-40W/ZLF application, or BC807-40W/ZLF equivalent, this page delivers verified electrical parameters, thermal derating behavior, SOT323 footprint details, and validated alternative transistors for discrete BJT selection in low-voltage analog and digital interface circuits.

Technical Context

This PNP transistor operates with open-base collector-emitter breakdown voltage of −45 V and emitter-base breakdown voltage of −5 V, supporting reliable cutoff and saturation in low-power signal routing. Its pulsed h_FE range (250–600) and −700 mV V_CE(sat) at I_C = −500 mA / I_B = −50 mA enable efficient current-controlled switching in logic-level compatible circuits.

Thermal resistance R_th(j-a) is 625 K/W on standard FR4 PCB and improves to 431 K/W with 1 cm² collector pad - directly informing layout-driven power handling. Transient thermal impedance curves confirm stable pulse operation up to 1 ms at 200 mA peak base drive.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−45 V: Maximum safe collector-emitter voltage under open-base condition; defines upper rail limit for PNP switch operation.
I_C	−500 mA continuous: Steady-state current-handling capability at T_amb = 25 °C; supports medium-current load switching.
h_FE	250–600 at V_CE = −1 V, I_C = −100 mA: Confirmed DC current gain range enabling predictable base drive sizing.
V_CE(sat)	−700 mV max at I_C = −500 mA, I_B = −50 mA: Low saturation voltage minimizes conduction loss in switching applications.
P_tot	200 mW (standard footprint) / 290 mW (1 cm² pad): Absolute maximum power dissipation limits PCB copper area requirements.
T_j	150 °C maximum junction temperature: Sets thermal design margin for ambient and board-level cooling strategies.
f_T	80 MHz typical at V_CE = −5 V, I_C = −10 mA: Transition frequency confirms suitability for audio and low-MHz signal amplification.

Pinout & Package

SOT323 (SC-70) plastic surface-mounted package with 3 leads; dimensions: 2.2 mm × 1.35 mm × 0.95 mm (L × W × H), 0.65 mm lead pitch, standard footprint per Figure 17.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Current-controlled input node; requires ≤ −12 mA peak drive for full saturation at I_C = −500 mA.
2	Emitter (E)	Common reference terminal for PNP topology; connected to higher potential rail in switching configurations.
3	Collector (C)	Output current path; electrically tied to load; thermally coupled to PCB copper for heat dissipation.

Key Features

Feature	Design Value
High h_FE grade	250–600 range ensures consistent base current scaling across production lots for stable biasing.
Low V_CE(sat)	≤ −700 mV enables <100 mW conduction loss at 500 mA, reducing thermal stress in compact layouts.
SOT323 footprint	0.65 mm pitch and 2.2 mm length allow high-density placement on 4-layer consumer PCBs without rework risk.
Robust thermal rating	150 °C T_j and defined R_th(j-a) values support operation in sealed enclosures up to 85 °C ambient.
Standard marking	"5C%" code (per Table 5) enables automated optical inspection and traceability in SMT lines.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP general-purpose transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BC807-40	Same electrical specs but in larger SOT23 package; 1.3 mm × 2.9 mm vs. SOT323's 1.35 mm × 2.2 mm.	Less suitable for ultra-dense layouts; better thermal performance due to larger pad area.	Select when board space permits and higher continuous power handling (>250 mW) is required.
MMBT3906	Lower h_FE (100–300), same −40 V V_CEO, −200 mA I_C; SOT23 package.	Limited to ≤200 mA loads; insufficient for 500 mA switching; not drop-in for high-current designs.	Choose only for low-current signal inversion where gain consistency below 100 mA is sufficient.

Compared with BC807-40W/ZLF, BC807-40 offers identical electrical behavior in a thermally superior but larger package, while MMBT3906 trades current capacity and gain for broader legacy availability - making BC807-40W/ZLF optimal for new designs prioritizing miniaturization and 500 mA capability.

FAQ

What is the maximum allowable base current for BC807-40W/ZLF in continuous operation?

The absolute maximum peak base current is −200 mA per Table 6, but continuous operation must stay within the DC-rated limits implied by power dissipation. At T_amb = 25 °C and standard PCB, P_tot = 200 mW constrains I_B to ≤ −20 mA for sustained use - verified by V_BE ≈ −1.2 V and thermal resistance modeling.

Can BC807-40W/ZLF replace BC807-25W in an existing design?

Yes - BC807-40W/ZLF has higher minimum h_FE (250 vs. 160) and identical V_CEO, I_C, and package, so it will deliver equal or improved current gain stability without circuit modification. No derating or layout change is needed.

Does BC807-40W/ZLF meet RoHS and REACH compliance?

Yes - Nexperia confirms BC807-40W/ZLF is RoHS-compliant (Pb-free, homogeneous material level) and REACH-conformant per its product change notification PN-000122, with full substance declarations available in the Nexperia Product Compliance Database.

What is the recommended solder profile for SOT323 reflow of BC807-40W/ZLF?

Per Figure 17 and Nexperia document AN10357, use JEDEC J-STD-020-compliant reflow: peak temperature 260 °C (max), time above 217 °C = 60–150 s, ramp rate ≤ 3 °C/s. The SOT323 footprint requires 0.55 mm × 0.6 mm solder paste apertures for reliable void-free joints.
